Abstract

The outcomes of the wastewater contaminated with antibiotics entering the WWTPs of Dar es Salaam city were examined. This study aimed at evaluation of the quality of the disposed treated wastewater in order to find out the fate of the antibiotics in the city WWTPs. Antibiotics amoxicillin, ampicillin and ciprofloxacin concentrations ranged from below detection limits (bdl) to 0.367 mg/l and bdl to 0.037 mg/l were measured in wastewater influents and effluents samples, respectively. In all the WWTPs, effluents concentrations were lower than their corresponding influents. Variations in levels of antibiotics in WWTPs were considered to be attributed to removal efficiency of individual WWTP and antibiotics prescription patterns in different locations of the city, which determine or affect influent concentrations. All the parameters were measured by standard methods.
